Answer:
Initial Velocity= 49 m/s
Time period= 5 secs
Explanation:
THIS IS THE COMPLETE QUESTION BELOW
A rocket shoots up 123 meters. What is it initial velocity?How long is it ascending
The initial velocity can be calculated using the expression below
u= √( 2gh)
Where g= Acceleration due to gravity= 98 m/s^2
h= height
Substitute the values we have
u = √(2*9.8*123)
u=√( 2410.8)
u = 49 m/s
the time period can be calculated as
(49/9.8)
= 5 sec
Hence time period is 5 secs
Answer:
$68,000
Explanation:
The long-term note payable is a debt that is formally established through a written agreement. An example of long-term note payable is a bank loan.
When the principal and the interests of a long-term note are paid, they represent Cash outflows from the business and are recorded in the Cashflow Statement. However, their treatments are different. Another way to put it is that they bring a reduction in the cash of the organisation.
The $68,000 principal amount paid is an outflow from the company that is recorded in the financing activity section of the Cash Flow Statement
The Interest of $5,440 is also an outflow from the business but it is reported in the operating activity section of the Cash Flow Statement. The reason for its report is that it is actually reported in the Organisation's Statement of Income as an expense for the year. It, therefore, qualifies as an operating activity expense or outflow.
Answer:
c. $150.
Explanation:
the extra amount of hours Maurice can work taking a flight will be of 5 hours
(8 hours taking a plane against 3 hours if driving)
As the income per hour is 30 dollar it can generate;
5 hours x $30 per hour = $150
Maurice will only travel by plane if it generates the same or more income than the driving thus, a differencial price of less than 150 dollars will provide Maurice with a net gain. Also we should consider that if Maurice drives his car it is taking a depreication hit per mile while driving that is being ignoer to keep the assignment simple. But considering that the amount of differential income could be higher than $150
Answer:
(B) $38,446,000
Explanation:
Assuming a linear depreciation model, depreciation will occur at the same rate each year. Since the total after 15 years is 90% of the original value, the percentage depreciated per year is given by:
The book value (V) of this purchase after the first year will be:
Therefore, the answer is (B) $38,446,000
Answer:
The male frog would join the female frog in the water poodle
Explanation:
Mathematically,
Let x = temperature the 10000 joules from sun Ray would raise the temperature of the copper
So therefore:
10000 = m * (x - 33°) * Spc
Where m = mass of copper = 400g
Spc = specific heat capacity of copper = 0.387j/g/°c
So
400 * ( x - 33) * 0.387 = 10000
( x - 33 ) = 10000/ (400 * 0 387)
x = 97.6 °c
Temp for water where m = mass of water = 100g
x¹ = temperature the sun Ray of 10000 joules would raise the temp of water too.
Spw = specific heat capacity of water = 4.184j/g/°c
So therefore;
100 * ( x¹ - 33 ) * 4.184 = 10000joules
x¹ - 33 = 10000/ (100 * 4.184)
x¹ = 56.9°c
Since x for the male frog is greater than x¹ for the female frog, the male frog would be more uncomfortable because it's environmental temp is far higher than the comfort zone tem which is 20° to 40°c so it would move to join the female frog.
